2016.08.22 - Scarf Joints Continued
I had good intentions to continue working on Naiad even though I was attending the re-enactment of the Battle of Bosworth in Sutton Cheney at the weekend but I was too busy to do anything other than think a few more things through. I took the mast hoops, canvas, leather and tools but did not even get the chance to look at them. Not really surprising since not only was I the cook for 17 of the group members but I was the event manager for Destrier as well. I and another member of the group seemed to spend a lot of time banging in tent pegs to stop the tents and awnings from blowing away. It was exceedingly windy and the pegs kept being pulled out of the ground.
Still, today I have been able to continue the task of scarfing various pieces of wood together.
The battens that were glued up last week were put through the planer this afternoon and you can see the result of one of them here. Notice that it is very difficult to see the join and it is most noticeable by the change in the grain of the two pieces rather than the glue line.
The other side of the batten is the same.
The second batten has not been planed in this photo and you can see the join more clearly here.
These four pieces of timber will become the rubbing strake and need to be joined to form two pieces long enough to be bent around each side of the hull. The timber will need to be steamed in order to make the bend without splitting and therefore resorcinol glue and not epoxy will need to be used to make the join. Resorcinol glue is not a gap filling glue and thus the two pieces to be joined must fit together as closely as possible. Just like the smaller battens.
The first piece in the scarfing jig and really to go.
All of the pieces now have one part of a scarf joint made in one end.
A slightly different view showing how repeatable the joint is when made using a jig.
The four pieces are glues together with a lot of pressure on the joint as per the gluing instructions and also to keep the pieces together in the correct place. No bends or kinks anywhere, I hope.
